Safety evaluation for prolonged gas pipeline operation in areas of high seismicity

Abstract: The article considers questions of changes in pipe steel properties of strength category K50-K56 during operation under conditions of the action of seismic loads. The limiting permissible number of loading cycles is shown for pipelines made from test steels with earthquakes of different intensity.Within the Russian Federation regions with seismicity of seven points and higher embrace about 2.3 million km 2 of area, which comprises more than 13% of the territory.
